Daily deals website Groupon Inc (GRPN) forecast a surprise loss for the current quarter as it spends more on marketing, sending its shares down more than 13 percent in extended trading.
The stock had briefly risen more than 18 percent in extended trading after the company reported better-than-expected fourth-quarter results helped by strong demand in the holiday season for its business that sells discounted products.
Groupon, which competes with Amazon.com, eBay and Google in a fiercely competitive online marketplace, will spend $25 million on marketing in the current quarter to drive growth, Chief Financial Officer Jason Child told Reuters.
"As we fold in our two new acquisitions, TMON (Ticket Monster) and Ideeli, we are going to be investing $20 million," Child said.
The company bought rival e-commerce company LivingSocial Inc's South Korean unit, Ticket Monster, for $260 million in November and Ideeli Inc for about $43 million last month.
